I was thinking of joining a spinning class because it's boring to ride on my trainer all the time, and I'd like to be able to have some sort of company. However, my bike has keo pedals, and therefore I have keo cleats, but the spinning bikes where I would be taking the class have different pedals, which aren't keo compatible. I'm pretty sure they're spd, but I have no idea. Would anyone recommend getting cleats that are compatible, and change them every class, and then change them back afterwords so that I could ride on my trainer other days? Or buying a new set of shoes or pedals, depending on which I can find cheaper?
